Organic zeolites porphyrins

Mineral Surfaces. Organic matter is chemically adsorbed (deriva-tized) at the surfaces of clay minerals, zeolites, and related minerals (105) and is at times protected, concentrated, and degraded by contact with the solid surfaces. For example, porphyrins are protected (106), as are optically active amino acids by montmorillonite (107). This may result in part from the position of the organic matter in lattice spaces, as shown by Stevenson and Cheng (108) for proteinaceous substances keyed into hexagonal holes on interlamellar surfaces of expanding lattice clays, or from the fact that there are ordered structures at solid-water interfaces (109). 

Other zeolitic materials with adsorbed porphyrins on external surface include the immobilization of Sn(TMPyP)Cl2 andSn(TPyP)Cl2onzeoliteYforuseasa solid photosensitizer material in the photodegradation of organic substrates. Zeolite supported Fe[T(n-MPy)P] (n =2, 3 or 4) was explored in heterogeneous catalytic autoxidations of sulfite.
